Also I've noticed an overall decrease in the price of the things I've ABed over the last few months. I think we actually suppress the prices by undercutting each other so much. Most people would get a r85 item and think it's the shit and hold on to it forever on the TP. I've personally deflated the price of several items by putting it in my shops and others started doing the same.
I've also noticed this trend. Do ABers tend to care less about the profit they make because they haven't invested so much of their time in restocking perhaps?
